AUTOMATIC STARTING nnvicn.

Specification of Letters Patent.

Patented Dec. 31,1912.

Application filed November 27, 1909. Serial No. 530,099.

To all aohom it may concern: i

Be it known that I, E oENIoCANToNo, a

subject of theKing of Italy, residing at Villa Serverina, VialeParioli, Rome, Italy, retired captain-of the engineers in the Royal Italian Army, have invented a certain new.

and useful Automatic Startin Device, of which" the following is a speci cation.

In the device covered by my U. S. patent filed on 22 June 1907,Ser. No. 380208, when the operatoris to recharge the spring, counterweight or similar device, by acting directly or by means of a suitable mechanical transmission he effects the alinement of the pivoting armswhlch carry the gear1ng-de signed to transmit the movement of the mo-' tor to the spring compressing rack. 7

My present invention has for' its object 'to provide 'a device for effecting th""said the lever is shifted to the broken line position 6 and lare out of mesh. The gear 2" 4 is loosely carried by the shaft B and meshes alinementautomatically after each distention of the spring.

Figure 1 shows "a side elevation of the device with the sp'ringcasing in section; Fig.

2 shows the secondary shaft carrying one of the operating levers; Fig. 3 shows one of the detents separately; Fig. 4 shows the.

notchedarm on the shaft; Fig. 5 shows the bent lever; and, Fig. 6 shows theprm for.

the spring on t-he'se'condary shaft.

In-the drawing, on the shaft B of the motor a lever A swingsfreely and carries at its-lowerend a pivot C on which rotates a gear 5 meshing with a gear fast on the motor shaft "B; 'Gear 5is' fast to a gear 6 .that' .meshes with agear .1' in the position of the lever A shown in full-lines, but when with'the rack J secured to the spring Z by which the spring is compressed upon rotav tion of said gears in one direction; Lever A has'a pivot E carrying link'F connecting by pin G with an arm H'swinging on a stationarypivot L.. Arm II also carries lug Y engaged by block X on rack J when the spring has been compressed to swing arm H.

On stationary axis 0 is mounted a crank le'ver S-P carrying a pivot N on which is.

pivoted the lever S. A pin M connects the lever S withlink R, the latter by pin Q being pivoted to arm HQ Shaft O has keyed thereto a lug T capable of engaging lug V- rigidly fixed to the rack. Lever SP is capable of passing with its pivot from'posrtion N to position N t On the motor shaftis a pivot 3 on which swings a pawl K that is thrown out by centrifugal force and engages the arm P in its lower or depressed position.

In the operation of the device, when th lever A has swung to bring gears-6 and 1 to mesh through. gears 1 and 2,gear 2 will advance the rack J to compress the spring Z. At the limit of this movement'block-X strikes lug Y and shifts the combination of links and lever from the full position in which it shows, to the broken line position The rotation of the shaft will throw outa pawl K that will strike the-lug P in the broken line pqsition and again shift the levers, causing the gears 5 and 1 to-be separated. When the spring Z is opening from its closed position, lug V will strike the arm T and rotate shaft 0 against the tension-of spring IV connected to pivot I This will swing the arm P away from the left hand position into-position to be struck by the pawl K, and the latter will engage causing the lever A to be shifted to bring thegears 5 and'l into mesh, causing thespring to be again put under tension.

. Having now fully described my inventionand the manner in which the same is to be performed, I declare that what I claim is: 1;In a starting device, the combination of a casing, a spring in the casing, a rack on the spring, a lug on each end of the rack, I

a motor shaft, an arm loose on the motor shaft, a gear pivoted on said-arm, a second shaft carrying a gear arranged to rnesh with said gear'on the arm in one pOSltlOll of the arm, a gear fast to the said gear on the arm,

a gear fast on the shaft in'mesh with the latterfgearfanot-her gear on the motor shaft meshin with said rack, a pawl on the motor shalt arranged to swing out by centrifugal force, an arm swinging on a stationary pivot, a link connecting said arm with said lever, a second arm swinging'on a stationary pivot, a link pivoted to the latter arm, a link pivoted bet-ween the latter ink and said first arm, a lug on the second link arranged to be engaged by said pawl. in one position, a lug connected with the second arm to be engaged by one lug on the rack, and a lug on the first arm arranged to be engaged by the other lug on the rack.

In a starting device, the combination of a casing, a spring'in the casing, a rack on the spring, a lug on each end of the rack.

a motor shaft, an arm loose on the motor the lattergear, another gear on the motor shaftmeshing with said rack, a pawl on Lthe motor shaft arranged to swing out by 10 centrifugalforce, an arm swinging on a stationary plvot, a hnkconnectlng said arm' with said lever, a second arm swinging on a stationary pivot, a link pivoted to the latter arm, a link pivoted between.the lat- 15 ter link and said first arm, a lug on the sec- Y inaaaoa 0nd link arranged to be engaged by said pawl in one position, a lug connected with the second arm to be engaged by one 111g on the. rack, and a lug on the first arm arranged to be engaged by the other lug on the rack, and a spring connected with the second arm normall retaining it in position to be engaged y its said In In testimony whereof-I have a xed my signature in presence of two witnesses.
